Lateralus

First released2001

Lateralus was recorded between 2000 and 2001 at Cali Tonalities in Los Angeles, with additional recording at other locations. The album was produced by Tool and engineered primarily by David Bottrill, who had previously worked with the band on Ænima. The band employed innovative recording techniques including the use of the Fibonacci sequence in song structures, most notably on the title track, reflecting frontman Maynard James Keenan's interest in mathematical patterns. The production process was notably lengthy and meticulous, with the band taking considerable time to refine arrangements and experiment with layering of instruments. The album marked a significant departure from their previous work in terms of both compositional approach and sonic complexity, utilizing advanced studio technology to achieve the intricate polyrhythmic and textural elements that define the record.
